PROBLEM TO BE SOLVED: To enable performing a characteristic test of a filter component with only the filter component mounted on a wiring board, in a high-frequency module having the wiring board having one primary surface on which a switch IC and the filter component are mounted.SOLUTION: In a high frequency module 1 including a wiring board 2 having one primary surface on which a switch IC 3 and a filter component 4 are mounted, switch electrodes 7b for mounting the switch IC 3 connected to one ends side of first and second filter circuits of the filter component 4, first to third test electrodes 6a to 6c connected to the other ends side of the first and second filter circuits, and a fourth test electrode 6d connected to a ground terminal 4e of the filter component 4 are formed on the one primary surface of the wiring board 2. This allows performing a characteristic test of the filter component 4 from the one primary surface side of the wiring board 2 by using the switch electrodes 7b and first to fourth test electrodes 6a to 6d with only the filter component 4 mounted on the wiring board 2. |
